Terms in this set (49)
Any disease that is caused by an agent that can pass from one living thing to another.
A disease that can be passed directly from one person to another person.
A one-celled organism that is found everywhere. Examples: strep throat, tuberculosis, sinus infections, tetanus, and ulcers.
An extremely small organism that consists of a protein coat and some genetic material. Examples: cold and influenza.
An organism that absorbs nutrients from its environment. Examples: athlete's foot and ringworm.
Usually single-celled organisms, most are free-living but some are pathogens. Examples: amebic dysentery and malaria.
An organism that lives in a host organism; draws nourishment from a host; some may be very large. Examples: tapeworm.
A widespread occurrence of a disease.
A drug that kills or slows the growth of bacteria.
The reaction of the body to a germ that has gotten in; made up of organs and special cells that fight infection. Without your immune system, your body would be powerless against most of the agents that cause infections and disease.
When a germ tries to invade your body, the first thing it comes into contact with is the skin. Your skin is actually made of many layers of cells. The cells on the outside are tough and dead, which makes it difficult for a germ to get through. These cells are also constantly flaking off, taking germs with them.
The hair around your eyes and nose traps germs and keeps them from getting into your body. The large airways of the lungs also have tiny hairs called cilia that keep germs out of the lungs.
Your eyes produce tears that wash germs out of your eyes.
The sticky substance that exists in your nose and other parts of your body is called mucus. Mucus not only traps germs but also contains chemical defenses to attack and destroy the germs.
Saliva and Stomach Acid
Most of the germs that enter your mouth and stomach are killed by saliva and stomach acid.
The Immune Response
Imagine that a virus has entered your body and invaded your body's cells. This is the immune response that would follow:
1. Cells called macrophages (MAK) engulf the cells that have been infected by viruses.
2. The macrophages signal cells called T cells and cells called B cells.
3. The B cells produce antibodies, which are substances that destroy germs. The T cells help destroy the virus-infected cells.
4. Antibodies attach to other viruses outside of the cells. This signals other cells to destroy the viruses.
If you once had a certain disease, you would rarely catch it again. Examples: chickenpox.
Caused by a bacterium called streptococcus.
Caused by very slow-growing organisms from a family of bacteria called mycobacteria.
Open areas in your skull that are located behind your face and above your mouth; can fill with mucus and become infected with bacteria.
A virus from one of two groups of viruses called influenza A and influenza B.
A substance used to keep a person from getting a disease.
Any harmful change in the state of health of your body and mind.
A disease that is not caused by a virus or living organism.
Sign of a Disease
Something another person can see or measure. Examples: fever.
Symptom of a Disease
A feeling of pain or discomfort you have when you are sick. Examples: sore throat.
An overreaction by the body to something that is harmless to most people, such as pollen or peanuts.
A brain disorder that gets worse over time and that affects a person's memory and behavior.
An abnormal reaction of the respiratory system that causes shortness of breath, wheezing, and coughing.
A group of diseases that can attack any type of body tissue, in which cell growth is uncontrolled.
Circulatory System Diseases
A group of diseases that affect the heart and blood vessels, such as hardening of the arteries, high blood pressure, and heart failure.
A group of diseases that cause muscle tissue to get weaker over time.
A characteristic or behavior that raises a person's chances of getting a noninfectious disease.
Weighing at least 20% more than your recommended weight; related to a variety of noninfectious diseases including Type 2 Diabetes, heart diseases, and high blood pressure.
To Treat a Disease
To provide medical care to someone who has that disease.
A disease caused by defective genes inherited by a child from one or both parents.
Control the activities of cells and determine a person's physical characteristics.
A.K.A. PKU; if left untreated, can cause mental retardation.
A.K.A. CF; people with Cystic Fibrosis may have trouble breathing.
The process by which the body converts the energy in food into energy the body can use.
The result of all processes, including digestion and metabolism, by which your body takes in nutrients in food and uses the nutrients to maintain your health.
Poor nourishment caused by a lack of nutrients.
Causes an allergy; almost anything can be an allergen.
A disease in which a person's immune system attacks certain cells, tissues, or organs of the body.
A mass of abnormal cells.
These tumors are cancerous and can be life threatening; spread to other parts of the body, invade other organs and tissues, and they tend to get worse.
These tumors are not cancerous and are usually not life threatening; do not spread to other organs or tissues.
Common Types of Cancer
In women: breast, ovarian, and lung cancers. In men: prostate, colon, and lung cancers. In children: leukemia.
Ways to Treat Cancer
1. Surgery - Doctors remove cancer cells from the body. This method works best on cancer that has not spread to other parts of the body.
2. Chemotherapy - Chemicals are used to destroy cancer cells. This method is used to fight cancers that have spread.
3. Radiation - High-energy rays from radioactive materials are used to shrink or kill cancer cells. This method is usually used in combination with surgery and chemotherapy.
